Product details
The CSB XHRL12250W is a 12V valve-regulated sealed lead-acid battery belonging to the XHRL series. This series is a high-performance variant of HRL, providing higher high-rate output for UPS and data center requirements. The battery uses absorbed glass mat (AGM) technology, with gas recombination efficiency up to 99%, a maintenance-free design, and pure lead construction with proprietary elements. Its official application area is data center uninterruptible power supplies, suitable for high-rate discharge and float standby scenarios.
In terms of electrical parameters, the XHRL12250W has a nominal voltage of 12 Vdc and a nominal capacity of 250W (1.67 VPC @25°C, 15-minute rate). The 5-minute rate power is 463.17 W/cell, and the 15-minute rate power is 252.67 W/cell (1.67 VPC @25°C). The maximum charge current is 25.00 A, the maximum discharge current is 650 A, the short-circuit current is 1680 A, and the internal resistance is 4.20 mΩ. The float charge voltage is 13.5 - 13.8 Vdc/battery (25°C), and the equalizing charge voltage is 14.4 - 15.0 Vdc/battery (25°C).
The battery's terminal type is I2 threaded lead alloy terminal, accepting M6 bolts, with a terminal torque of 51.7±10.3 Kgf∙cm or 44.9±9.0 Lbf∙in or 5.1±1.0 N∙m. The case material is PP (UL 94-HB), and a flame-retardant version (94-V0) is available upon request. The weight is 18.52 kg (40.82 lb), and the dimensions are length 228.0±2.5 mm, width 138.4±1.5 mm, height 206.3±2.5 mm.
In terms of design life, the XHRL12250W can reach 10 years in float standby service at 25°C, meeting the Eurobat standard (20°C) very long life classification of greater than 12 years. The operating temperature range is: nominal 25°C, discharge -15°C to 50°C, charge/storage -15°C to 40°C. The self-discharge rate is less than 10% after 90 days at 25°C, and it can be stored for up to 6 months, requiring a full charge before use; if the storage temperature is above 25°C, charge in advance.
This battery is manufactured according to IEC 60896-21/22:2004 and is recognized under UL1989 (MH14533). Its high-rate discharge characteristics make it suitable for data center UPS and other applications requiring reliable standby power, meeting the requirements of float service standby applications.
